' BALL-Bunnie I anion.

ZOrlglnal application fled December 14, 1923, Serial No. 680,800.Divided and this application fled August 26, 1828.

My invention relates particularly to door hinges or butts and thisapplication is. a division of 680,600 filed December 14, 1923.

One object is to reduce the friction'to a 5 minimum.

One object is to provide a simple but reliable construction which caneasily be handled without losing the parts.

Another object is to provide a construc- 10 tion which .is cheap butdurable. Another object is to provide a hinge which'can be reversed.Another object is to provide a hinge whichvcan be readily lubricated.

Another objeEt' is to provide a bearing in 1 which the balls at oneendof a knuckle may be replaced without disturbing those at the otherend. 1 i Y In the preferred form the bearing unit is held in place byasleeve or tube spun over '2 or upset over the inner edge of the unitleaving the outer washer free to rotate.

Fig. 1 is a side view of ahin ing my invention. 7 V v ig. 2 is avertical. section of a fragment 25 on the plane of the line 22..wofFigure 4'.

Fig. 3 is a side view and section showing a fragment of one hingeknuckle and its sleeve and a bearing unit. 1

Fig. 4 is a plan view of one knuckle and 30' its'sleeve. v

Fig. 5 is 'a vertical sectional view of a modification..-'

In the form shown the leaf 6 has knuckles 7, 8 and 9' and leaf 10 hasknuckles 11' and 35 12 and they are held together by a removable pintle13.nsually locked or secured to the upper knuckle 7 so as to turn orremain stationar is customary.

Each bearing unitconsist of an inner hardened washer 14 an an outerwasher 15 with balls 16 between them and enclosed by a housing or casing17 which embraces the edges but is loose enough to rmit the .46 outerwasher toturn freely. Thls housing may have any finish desired. Itcovers the sides of the space between the washers so as to keep out dirtand keep in the lubrieating material commonly employed. The 60 bearinunit is-held in place on the knuckle 8 by t e sleeve or tube 18, the end19 of which is turned over at 20 into the locking recess 21 at the inneredge of the inner ge embody Ordinarily the bearing u y with the leafwhich carries it as- Serial Io. 181,862.

washer 14.- This holds the washer 14 against the knuckle 8 in which thesleeve is mounted 56 so that there is no relative movement between thepintle 13, thejsleeve '18 and the lower bearing washer 14 It will beseen that there is aspace 22 in the u pet or outer washer 15 throughwhich a In ricant can be inserted 'into the ball hearing when the intleis re- .moved. The load from the knuc le 11 is carried by .the upperwasher 15 and'thence to the balls 16, washer 14 and knuckle 8.

Preferably another bearing unit is mounted on the-lower end of theknuckle 8. The sleeve 18 serves to hold the washer 23 in place in thesame mannenas it holds the washer 14. The housing 24 holds the washer 25and encloses the balls 26. In case the leaf 10 is fixed and the dooriscarried by 3 the leaf 6 the principal load of course will come on thislower bearin unit. I In the form-shown in igure 5, the tube or sleeve'30which holds the upper unit 31 has spring fingers 32 which engage in arecess 33 in the knuckle 34. The lower unit 35 is similarly held by asplit sleeve36. In each case the bearing unit has an opening 37 or 38for access.

nit will'be completely assembledbefore attachment to the knuckle. Theinner' washer however, can be attached first and the ,balls, outerwashers and housing added.- The hou'singcan be removed b springing itslightly so as to replace ba ls if needed.

I claim:

1. A I hinge consisting of leaf members having overlapping knuckles, a'pintle and I10 a bearing 111111, on the pintle between the knuckles saidbearing unit having a assage; and] comprising two hearing. was ers, ball'members between the washers and a housing'holding the washers together,and and "a tube'secured within one knuckle and having one end extendingpart waythrough I ,the bearing unit and flanged within the bearingunitto hold it in place and leaving the inner .edge of the outer washer freeto, permit lubrication of the ball members and races without disengagingthe bearing unit from the tube.

2. 'A' hinge comprising a leaf having a knuckle with a passage, abearing unit on the, knuckle comprising top and bottom washers, ballsbetween the washers and a housing enclosing the outer edges of thewashers, the bottom washer resting directly on said knuckle, and a tubewithin said passage having its upper end secured to the bottom washerand leaving the top washer free to turn and a pintle extending throughsaid tube and spaced away from the top washer.

3. A hinge comprising a leaf having a knuckle with a passagetherethrough, a ball bearing unit mounted on each end of the knuckle,each unit consisting of inner and outer members, balls between themembers and means for securing the members to gether, the inner membersengaging the ends of the knuckle, a sleeve within theknuckle passagehaving its ends projecting into the inner members of the bearing unitsand flanged over to hold them in place, the outer members being free toturn independently of said sleeve.

4. A hinge comprising a leaf having a knuckle with a passagetherethrough, a bearing unit mounted on one end of said knuckle andconsisting of an inner and an outer I member with balls between them,the inner a locking terfitting knuckles, bearing washers mounted onopposite ends of one knuckle, a sleeve in said knuckle having its endsturned over the inner edges of said washers to hold them to saidknuckle, an outer bearing washer arranged between each of the innerwashers and the adjacent knuckle, ball bearings between the outer andinner bearing washers and a pintle securing said knuckles in alinement,said sleeve and the connected inner washers turning with the pintle andthe outer washers turning with the adjacent knuckles. p

6. A hinge comprising leaf members hav lng over-lapping knuck es withaligned passages, a ball bearing unit between adjacent overlappingknuckles and with a passage in alignment with the passages in saidadjacent knuckles and comprising an outer bearing with respect to one ofsaid 'knuckles,

and other parts including an inner bearing. a series of balls betweenthe bearings and an external housing holding said outer and innerbearings together, and means for securing said bearingunit to thecorresponding adjacent knuckle including a tube within and extendingfrom the passage of such adjacent knuckle and interlocking with one ofsaid other parts while leaving said outer bearing free to turn with theother knuckle independently of the tube.

7. A hinge comprising leaf members having overlapping knuckles withaligned passages therein, an anti-friction bearing unit between adjacentoverlapping knuckles and having a passage in alignment with the alignedpassages in said adjacent knuckles and comprising two bearing members,devices adapted to roll between said bearing members and a housingenclosing the outer edges of and holding said bearing members together,means for securing said bearing unit to one of said adj acent'knucklesincluding means separate from and within the passage walls in suchknuckle and extending therefrom into the passage in the bearing unit andinterlocking with an inner portion of said bearing unit while leavingthe outer bearing member free to turn with the other of said adjacentknuckles, and a pintle connecting said adjacent knuckles and passingthrough said bearing unit. v

8. A hinge comprising leaf members having overlapping knuckles withaligned openings, a bearing unit between adjacent overlapping knucklesand comprising two bearing members with devices adapted to roll betweensaid bearing members and a housing holding said bearing members togetherand enclosing the rolling devices, and means for securing said bearingunit to one of said adjacent knuckles including a separately formedtubular member secured within such knuckle and extending therefrom onlypart way through the bearing unit and part way to the inner surface ofthe outer bearing member and formed 'totoverstand an inner portionof-said bearing unit and hold it in place relative to the knuckle whileleaving the outer bearin member free and a pintle connecting saidknuckles and passing through said bearing unit.
